Question about 1994 Ford Aspire
I've been trying to get the timing procedures for this model, as I have a 94 aspire. sounds like you have something (a timing light) hooked up and can see the the timing mark moving, but I assume when you say you've shorted st1 to ground, that eliminates the computer control of idle. So the the computer is out of the equation, right? Or is it not electronic ignition?
I have eliminated some idle roughness by cleaning and setting spark plug gap, new air filter, and if its time, a new gas filter. Then, cleaned the sensors inside the air filter compartment, and the intake manifold. I'd heard of using wd40 on the same part of a taurus referred to as a oxygen sensor. But eventually, cleaning the plate that opens to let oxygen into the intake manifold is a good idea. I have 160,000 miles on my aspire ( 4 door hatchback 5-speed manual) and it gets 49 mpg on trips. I replaced the gear oil with mercon dextron last winter, It may have helped increase a few mpg. Also, check for vaccum leaks in your vaccum hoses. that's all I can think of right now.
